| Research Abstract |
To tackle water and food deficit in drylands, I devised agricultural practice to enhance water use efficiency with conserving water resources and increasing grain yield of crops by defoliation. Pot and field experiments were conducted in Japan and overseas to demonstrate the effects of defoliation and elucidate its theory. I found that defoliation in booting stage under drought stress can increase grain yield of sorghum. This increment may attribute to mitigation of sterility, maintenance of photosynthetic rate through high stomatal conductance, and allocation increase of assimilates to spike.
